FAQ

How do BASE period underwear work?

Aisle BASE period undies feature a specially-engineered lining that combines super-absorbent Truetex™ technology with a leak-proof layer to keep you dry and feelin’ fly.

Do your period underwear contain PFAS?

<b>No detectable levels of PFAS</b> have been found in our underwear, based on a detectable limit of one part per million

Do I need to wear a pad or tampon with them?

Our period underwear are designed to be worn on their own, but they make great backup protection for a tampon or menstrual cup too!

How do I wash my Aise BASE undies?

Rinse the gusset in cool water before washing in the machine with your regular laundry. Hang to dry where possible - it saves energy and prolongs the life of your undies! Just make sure they’re fully dry before storing or reusing.

Are BASE underwear compatible with Aisle Boosters?

We kept it super simple and streamlined with BASE undies, so you can just put 'em on and go. There are no pockets in the gusset of BASE undies so there's no need to use Aisle Boosters.

Great bikini

I normally am not a huge fan of the bikini fit, but I grabbed these on sale and they work for me! I did size up (S, I would normally be XS) to get the right fit. I like the lighter / sportier style of the BASE line!

Work for bladder leaks.

I was looking for underwear to help with light exercise induced bladder leaks and these fit the bill. Not bulky and good coverage.

Comfy and secure

I pair these with my menstrual disc and wear them on their own on light flow days. They fit true to size and I feel confident that I'll have no leaks.
